I stayed for almost 3 weeks in Korawin apartment and it was such a great pleasure. The location is superb just 5-10 Mon walk to terminal 21 mall and 1 min away from Korean and Japanese restaurants. There are plenty of taxi and motorbikes taxi outside and eventough it's central location it's so quite. Everything I have asked Korawin and he answered right away, and when the shower head broke he replaced it right away.
Apartment is really big 2 persons will feel really comfortable.
I'm sure next trip to Bangkok I will check the availability of this apartment first.
Thank you Korawin and your dad :)
